What Size Solar Panel Do You Need for Camping?

As camping enthusiasts, we’re often drawn to the beauty of nature and the simplicity of living off the grid. However, in today’s digital age, we still crave some of the modern comforts even while exploring the great outdoors.

That’s where solar panels come into play. Solar power allows us to harness the energy of the sun to power our devices and appliances, making camping trips more enjoyable and sustainable.

The ideal solar panel sizes for camping are broken down into various uses:

  • Minimal use (smartphone charging, charging small battery pack): 10-20W solar panel
  • Moderate use (charging multiple devices and/or power bank): 50-100W
  • Heavy use (charging a portable power station or large battery): 100-200W

What Wattage Solar Panel Do You Need for Camping?

The wattage of the solar panel you need for camping depends on your specific power requirements. To determine the appropriate wattage, make a list of the devices you plan to charge or power during your camping trip and note their power consumption in watts. Add up the wattage of all the devices to calculate your total power requirement.

As a general guideline, it’s recommended to choose a solar panel with a wattage that is equal to or slightly higher than your total power requirement. This ensures you have enough power to charge your devices, even on days with less sunlight.

However, consider the balance between wattage and portability, as higher-wattage panels tend to be larger and heavier. If mobility is a priority, you may opt for a smaller wattage panel and charge devices during periods of peak sunlight.

Understanding Solar Panel Sizes

In this image, I’m charging my EcoFlow River Max with two Elecaenta panels. They are each rated at 120W output. These are my favorite portable solar panels (hence why I have two!) because they are inexpensive and efficient.

When it comes to solar panels, their size refers to their power-generating capacity, which is measured in watts. The larger the panel, the more electricity it can produce. However, it’s crucial to strike a balance between power requirements and portability, as you’ll need to transport the solar panel to your camping destination.

Rated Wattage vs Realistic Wattage

From my experience testing, reviewing, and comparing multiple portable solar panels, make sure to note that you’ll typically receive anywhere from 50-80% of the rated wattage of the solar panel when you’re out camping.

For example, a 100W solar panel may only produce 50-80W of power. This has to do with several factors, such as the quality of sunlight on a given day and the angle of the panel towards the sun.

However, the most important factor affecting the realistic solar panel output you’ll receive has to do with something called Standard Test ConditionsOpens in a new tab., or STC. This is essentially how solar panels are graded in terms of output wattage.

Generally speaking, the STC for solar panels is equivalent to nearly perfect sunlight conditions. This isn’t a bad measurement scale, as it measures the near-maximum solar panel output. However, without understanding STC, one might expect their panel to consistently reach its rated output.

Minimum Solar Panel Size for Camping

The minimum solar panel size needed for camping depends on your specific power requirements and the devices you plan to charge or power.

If you have minimal power needs and only intend to charge small devices like smartphones or LED lights, a portable solar panel with a wattage between 10-20 watts may be sufficient. These smaller panels are lightweight, compact, and easily portable, making them ideal for backpacking or short camping trips. Some examples of these small panels are Goal Zero’s Nomad 7 and Nomad 10.

However, it’s important to assess your power consumption accurately and ensure that the panel’s wattage aligns with your needs. Keep in mind that larger devices or appliances with higher power requirements, such as laptops or portable refrigerators, will require a more substantial solar panel to meet their charging demands.

In these cases, it’s typically best to use your solar panel to charge a portable power station, which you can then use to safely power/charge your larger devices and appliances.

Energy Use – Calculating Your Power Needs

When camping, solar panels can be used to charge a variety of devices such as smartphones, cameras, tablets, portable speakers, and even power banks. They can also power LED lights, fans, or small appliances, depending on their wattage and capacity.

To determine the right size solar panel for camping, you need to consider your power requirements. Begin by listing the devices and appliances you plan to use and their power consumption. Most devices indicate their power requirements in watts. If you can’t find the wattage directly, you can multiply the voltage and amperage to get the wattage (W = V x A). Once you have the wattage for each device, add them up to get your total power requirement.

Factoring in Sunlight and Usage

Solar panels generate electricity by converting sunlight into usable power. However, the amount of sunlight you receive will vary depending on your camping location and the time of year. Keep in mind that solar panels are most effective when they receive direct sunlight. Consider the average sunlight hours and weather conditions of your camping destination to estimate the energy output you can expect.

To account for fluctuations in weather and ensure a steady power supply, it’s generally recommended to oversize your solar panel system. A good rule of thumb is to choose a solar panel with an output that is 1.5-2 times your total power requirement. This extra capacity will help compensate for any inefficiencies and ensure you have enough power even on cloudy days.

Portability and Setup

For camping, portability is a crucial consideration. You’ll want a solar panel that is lightweight, compact, and easy to transport. Look for foldable or portable solar panels that are designed specifically for outdoor activities.

These panels are often made of lightweight materials and come with convenient carrying cases. My personal favorite portable solar panel is a larger model, the Elecaenta 120W, which folds four times over and has a carrying handle. Additionally, consider the ease of setup. Look for panels that are quick to deploy and require minimal assembly.

For some more examples, I have a separate post you can check out where I share nine different portable solar panel models ranging from 14-100W.
